   I just installed the files on hp400.tar.Z (from altdorf) on my Bobcat
   (HP9000/360) system under HPUX 7.0, and am having problems.  It dies
   with an illegal instruction trap (SIGILL) while trying to load the
   runtime.com band.

   Has anyone else had this problem?  Perhaps the compiled band was built
   on a 68040 machine?  Or is it that we're running HPUX 7.0, while the
   distribution wants 7.0.5?  Any help would be appreciated.  I suppose I
   could rebuild the entire compiler and compiled runtime using the
   interpreter and the .psb files, but that could take days on a 360!

   thanks,
   Erik

The distributed binaries require 7.0.5 because they use a system call
that is not available in earlier releases.

Since that system call is only needed for 68040 machines, you can work
around the problem by rebuilding the executables from the sources.  It
will be compiled without reference to the system call, and should work
fine on your machine.
